What makes the SS‑F5 stand out

  • Integrated cell‑to‑pack design — fewer internal modules, improved structural integrity and simplified manufacturing for consistent performance.
  • All‑in‑one control — power electronics and the BMS are combined in a single unit, eliminating the need for an external switch box and streamlining installation.
  • Lightweight, high energy density — plastic housing reduces weight to 45 kg and improves energy‑to‑weight ratio for easier handling.
  • Robust safety features — precise cell balancing, DC‑side arc fault detection and reliable thermal performance reduce risk and support long, safe operation.
  • Scalable — parallelable with other units for larger capacities (check documentation for limits).
  • Easy installation & maintenance — MC4 quick connectors, a clear LCD showing SOC and error codes, plus remote monitoring via CAN2.0 / RS485.
  • Durable — long cycle life and a 10‑year warranty provide strong lifecycle value.
  • Weather‑resistant — IP65 rating and wide operating temperature range make it suitable for many environments, up to 3,000 m altitude.
  • Refined appearance — brushed metal front panel that fits modern home aesthetics.

Deye SS‑F5 is a compact, efficient LiFePO₄ home battery engineered for safety, longevity and simple integration with residential solar. It’s an excellent option for homeowners who want reliable backup and higher solar self‑consumption with minimal installation complexity.
